RESILIENT WHEEL- Specification of Letters Patent.

Patented Mar. 30, 1915.

1 Application filed December 5, 1912. Serial No. 735,166.

T all whom it m (l concern Be it known that I, EUGENE A. PALMER, acitizen of the United States, residing at Belle Plaine, in the county ofBenton and State of Iowa, have invented a new and useful ResilientVheel; and I do hereby declare the following to be a. full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a new and useful residient Wheel.

One of the features of the invention is the provision of a series ofspokes constructed of a continuous strip of spring steel sheet metal.This strip of spring steel sheet metal is constructed to form a seriesof substantially elliptical loops, the ends of which are offset from therim of the wheel, so that the arches of the loops may freely yield, inorder to insure the resiliency of the wheel.

Another feature of the invention is the provision of novel means forholding the portions of the sheet steel strip in place. 7

There are disclosed in the drawing certain features -of construction,but in practical fields these features may necessitate alterations, towhich the patentee is entitled, provided the alterations fall within thescope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :Figure 1 is a view in side elevation and partly insection of the improved resilient wheel, showing the construction of therim adjacent the substan tially elliptical loops. Fig. 2 is a transversesectional view through that portion of the structure of Fig. 1 which isshown broken away and in section.

Referring to the drawings 1 designates the rim of the wheel, which ischanneled out to receive any form of tire, whether it be, a hard rubber,leather or pneumatic tire 2, it being immaterial as to what character oftire and rim is used. A strip of resilient spring sheet steel 3 isprovided, which is constructed into a series of substantially ellipticalshaped loops t, the end portions 5 of which are offset or spaced fromthe rim, in order that the arches 6 of the substantially ellipticalloops may freely yield. These arches 6 are partly seated in recesses ofthe rim 1, which recesses are the center of the Wheel are broughttogether as at 13 for substantially half the radius of the wheel, toform the spokes 14. Each portion 13 of each spoke is connectedintegrally by the portion 15 to the succeeding portion 13 of the nextspoke. In this manner it will be seen that the spokes and the loops areconstructed of a continuous strip of sheet spring steel. The portions 15are constructed concentric with the bushing 16 of the hub of the wheel,and engaged therewith, as shown in Fig. 1. Fitting the bushing 16 of thehub on each end thereof is a sleeve 17 having an integral collar 18.These collars 18 of the sleeve are provided with radial recesses 19 toreceive the spokes 14, so as to hold the portions 13 of said spokesclamped together securely. Passing through the collars 18 are bolts orother suitable means 20 having nuts 21, whereby the structure of the hubis held together securely.

Arranged in the recesses 7 are filler blocks, constructed of fiber orany other suitable material designated by the numeral 7", for thepurpose not only of cushioning the parts of the wheel at such points,but also to render the wheel noiseless. In other words, to preventrattling and the like. Arranged between the arched portion 6 of theloops and the plates 8 are fiber fillers 7 which likewise cushion theparts of the wheel, as well as rendering the wheel noiseless. Therecesses or pockets 7 extend just slightly beyond Where the archedportions 6 of the loop engage the fiber filler 7, that is, when thewheel is not in action, so that when the wheel is in action, the archedportions 6 of the loop will always engage the fiber. It "will also benoted that the fiber filler blocks 7 are slightly recessed to receivethe arched portions 6 of the loops.

The'invention having been set forth, what is claimed as new and usefulis In combination, a hub member, spokes extending therefrom and havingsubstantially elliptical shaped loops at their outer portions, a rimhaving a series of elongated pockets gradually mergin into the surfaceof the rim, fiber filler bloc s in said pockets and terminating slightlybeyond where the 5 arches of said loops normally engage, the

sides of said pockets acting to prevent twisting of the filler blocks.said filler block having recesses to receive the arches of the loops toprevent their twisting, clamping plates 1 10 for holding the arches inplace, fiber fillers between the. plates and the. arches, and

means for clamping the rim, the first filler block, the archer portionsof the loops, the second fillers and the plates together.

In testimony whereof I have signed my 15 name to this specification inthe presence of two subscribing witnesses.
